Dell XP 13 7390 late 2019 and Linux

Since my 3 years old Macbook Pro 15inch got the flickering bug I decided to buy a Dell laptop. Why? I have a really old Dell laptop from 2004, and works perfectly as a OpenBSD firewall and internet router in my weekend house. After I got my machine, first thing was to install PopOS. Or better, I tried . It never worked, I think it's a bug in the loader section of PopOS, a bugreport is open. After some hours of hacking and fixing I got a bit bored and used a Ubuntu installation, which worked out of the box perfectly. Yes I know I had could bought the XPS at Dell with Ubuntu on it. But I did not want to ;) Here are some tricks to get the XPS smoothly running - right now I have the book attached to my curved 4k monitor and code some infrastructure stuff for infinimesh . 1. Bluetooth mouse First time a BT mouse is connected it lags. Moving the mouse, the pointer follows after seconds, slow and unresponsive.  Fix by sudo vi /var/lib/bluetooth/<MAC Adapter>/<MAC mouse>

OSX - iCloud accounts broken after update to Catalina

Yay - that was happen to me. Magically I had two iCloud accounts, both not working - and no way to delete one of them via Settings -> Internet Accounts. After a few hours of googling, debugging I got it working again. And as usual I'd like to share that solution, I think I'm not the only one with that problem ;) Be aware, that's a bomb solution, means it will reset all internet accounts - but also unfreeze all the broken stuff: sudo -v ; killall -9 accountsd com.apple.iCloudHelper ; defaults delete MobileMeAccounts ; mkdir ~/Library/Accounts/Backup ; mv ~/Library/Accounts/*.sqlite* ~/Library/Accounts/Backup/ ; killall -9 accountsd com.apple.iCloudHelper ; sudo reboot So, why does that happen? Apple uses sqlite as backend for storing the informations, and sometimes this single instance get corrupted. Have fun!

Enabling IoT to establish a sustainable value chain

I wrote an article for CIO Applications, here's archive of it IoT devices are getting more and more intelligent and can now create meshed networks by itself, switching from a sensor into an actor and transferring informations only for the meshed neighbors. For example a connected car could tell the future home that the homeowner will be at home in 5 minutes and the garage door and the door need to be unlocked in time, the lights need to be switched on and the grid operator needs to be informed that the wallbox now charges with 22KW. In near future this will happen over direct meshed information cells, operated by always connected devices, wearables, sensors, actors, mobile devices - short: everything. And all cloud provider offer dozens of solution to master the challenges, on the one, other or complete different way. Self-organizing mesh networking and communication comes with a permanent flow of information, massive IoT data streams even classic Big Data frameworks like Hadoop

Infinimesh IoT / IIoT platform is starting up!

Today is a day we will never forget - infinimesh ( https://www.infinimesh.io/ ) is starting and lifting off! Our Kubernetes, Apache Kafka ® and graph based Industrial IoT platform is entering the alpha stage! We have been working like maniacs over the past 14 months to bring a fully flexible, independent, patent and vendor lock-in free IoT platform to you! Soon it’s your chance to test and try it out, our closed alpha will be open for public on March 30, 2019 - Mark this date in your calendar! An incredible platform comes to life We believe smart and connected devices bring our society forward. Smart technology uses resources only when they are really necessary and thus prevents waste. On the other hand, when really required, smart things act and hence prevent accidents or simply enable a great user experience. We have started infinimesh 100% Open Source, without patents or closed software. Any software components we have developed, and to this we commit going forward, will be open -
